I'm going to be building a i7 probably 920. Going to wait an let you guys figure some stuff out first, good luck.

Here is a question that I havn't seen addressed or maybe it shows my ignorance, :p

Question/ Comment:

Since you don't really have to oc the memory too much.

Has anyone seen Temp differences in the CPU by running higher memory volatges?
I'm not really sure if they are related. I know they have intergrated memory controllers wondering memory voltage makes a difference.
 
I would guess you are going to have a hard time finding anyone that has tried overvolting past 1.66v. Intel has been very adamant that if you pass this threshold you will damage your chipset. (Which may or may not happen) But with the limited benefit to push the limit I'll be surprised if you find people willing to do much with the memory voltage.

I know I'm to cheep to risk it.
 
I guess my major point would be...

Find low voltage memory if it reduces temperature so that you may increase core and frequency. (not sure if thats possible yet, I'm thinking something about this might come up with better memory etc).

I would probably be on of the first things I'd check, 1.65v vs 1.5V (with terrible timings etc).
 
Yes, we are using up to 2.0v in some cases. The highest I have gone so far was 1.8 trying to get 3600mhz Uncore stable with 4.2ghz with HT running 8 thread software. The key is to keep QPI/VTT within 0.5 volts -max- from the DRAM voltage. The max recommended value for QPI/VTT is 1.35v by Intel but G.Skill tech support has stated that you can raise it as long as you have good cooling on the motherboard and you keep it within 0.5v of the memory voltage.

For example: 1.65v memory voltage is 100% safe as long as your QPI/VTT voltage isn't less than 1.15v. Using high QPI/VTT voltages to get stable at high overclocks at the high memory speeds which require high memory voltages may not be safe long term, nobody knows yet.
